IMPROVEMENT IN APPARATUS FOR DRESSING SILK THREAD, 80C.

Specification forming part of Letters Patent N0. 49,2110, dated August 8, 1865.

and Im parting Luster to Threads ot' Spun Silk,

85e.; and I do hereby declare and ascertain my said invention, referring to the accompanying drawings, in which- Figure lisa side elevation. Fig. 2 is a plan.

Fig. 3 is a perspective view-of the apparatus. y

My invention is for the purpose of laying the tine fibers smoothly upon the thread of silk, 85e., and giving the same a luster and polish, or even appearance. Heretofore it has been common to pass the rough threads through gum, and thence wipe them oi` by means of flannel or Sponges; but there has been some trouble in drying the threads so treated and giving them the proper gloss. To effect the drying and finishing, resort has been had to heated plates, over which the threads, after gumming, have been passed to dry and polish them; but this I consider defective and liable to injure the material.

To obviate the detects of the modes heretofore in use, I have made my improvements, which prepare the threads properly and finish them perfectly without the possibility of injury, by which they are materially improved in quality and value.

ln my improved method of treating threads they are 'rst wound on spools suitably arranged on wires placed in a frame, E, similar to those used in the silk trade, and shown at s sin the drawings. The threads pass oft' from the spools Sto the reservoir P ot' gum-solution or other suitable material already known and used for the purpose ot' finishing silks, &c. The threads are immersed in the liquid in the reservoir P by passing under a glass rod fixed The reservoir has a double bottom,

bymeans of whichthe solution contained therein may be readily heated by means of hot air l conducted through a pipe, N, from the airheater, to be hereinafter described. The threads then pass out of the solution `over flannels or sponges, or other suitable materials used by finishers of silks, 85e., and the threads are thence conveyed through proper guides, K, into and through an oblong box, D, Where they pass over and under certain glassods Gr G and out through other guides,/Kl,/to a reel, M, on which they are wo In passing through the wooden box D they receive upon them a current of hot air, blown in jets through a series of holes in the tube L, located at one end of the box D. This tube L connects with a proper air-heater, which in the drawings is a coil of tubing located in an ordinary stove, F. The air should be forced into and through the heater by means of any convenient blowing apparatus, such as a pump, as seen in the drawings at A, or a fan-blower or bellows, all of which may be driven and the reel turned by any convenient power, or by hand.`

ln this description I do not wish'to be understood as confining myself to the particular kind ofair-heater or mode ot making the-blast,

as they may be done in any convenient known way.

Having thus fully described my improved apparatus for dressing, inishing, andimparting luster to threads ot' silk and like material,

what I claim therein as new, and for which I g desire Letters Patent, is-
